Description
The TS187x (single, dual and quad) can operate with voltages as low as 1.8 V. They feature both input and output rail-to-rail.
The common-mode input voltage extends 200 mV beyond the supply voltages at 25°C, while the output voltage swing is within 100 mV of each rail with a 600 Ω load resistor. The devices consume typically 400 µA per channel while offering
1.6 MHz of gain bandwidth product. The amplifiers provide a high output drive capability at typically 65 mA loads.
These features make the TS187x family ideal for sensor interface, battery supplied and portable applications.

|
1.All voltage values, except differential voltages, are with respect to network terminal.
2.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If
Vid > ±1 V, the maximum input current must not exceed ±1 mA. When Vid > ±1 V, add an input series resistor to limit the input current.
3.Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers.
4.Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5.Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.
6.Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to ground through only one pin. This is done for all pins.
7.Short-circuits from the output to VCC can cause excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
